We were lucky enough to be able to spend a week in Scapa (N Scotland) last week.
Mixed group of oc and ccr depths from 25-45m 2 deco dives per day on average and either ascent via the shot or on SMBs depending on the dive, conditions etc.
A relatively hot topic for the week was how hard it is to actually hit and maintain a 9-10m ascent rate to the first stop.
Logging dives daily and comparing profiles we were all mainly averaging circa 6-8m per min.
If we did hit 9m a minute it felt pretty fast and unstable and was really only achievable on the shot ascents generally not during an SMB ascent.
Just wondered how others hit the prescribed 9m/min in ow.
In OHE the issue could be more pronounced given the profile of the cave or mine, and the slower the ascent the closer the deco profile strays towards a deep stop style ascent.
So does the computer adequately pad the shallow to reflect the slower ascent, or do you pad it to compensate?
